SPECIFICATION forming part of Letters Fatent No. 581,998, dated May 4, 1897.

Application filed January 5, 1895. Serial No. 583,926. (No modelfl To ttZZ whom it may concern:

Be it known that I, Josnrn F. Rnnnns, oi' the city, county, and State of New York, have invented a certain new and useful Improvem ent in Automatic Photographing-lilachi nos, of which the following is a specification.

My invention has for its object the prod uction of an automatic photographing-maehine in which the action of the various operative mechanisms are in part controlled by a suitable fluid under pressure as distinguished. from rigid connections.

The invention further provides, in combina tion with the foregoing, a motor of any suitable construction which is adapted to so control and regulate the flow of the fluid. under pressure to the various operative parts that the latter shall perform their several functions in their proper sequence. Means are also provided by which the operative parts of the machine are set in motion by the insertion of a coin of proper value.

. I will describe an automatic photographing machine embodying my improvement, and

then point out the novel features in the claims.

In the accompanying drawings, Figure l is a sectional elevation taken on a plane paral lel to the side of the machine. Portions, however, are in this figure shown in full side view. Fig. 2 is a rear View of the machine, the rear Wall of the inclosing case being removed and some parts beingshown in section. Fig. 8 is a plan view of a plate-holder comprising a pair of jaws and means for operating the same comprised in the improvement. Fig. t is a plan view showing an approved method of imparting to the plate magazine or box a step-by-step forward movement. Fig. 5 is an outline. View of a series of cams and their coacting parts. Fig. (3 is a longitudinal section showing the constructionof an engine which may be utilized for actuating any of the mechanisms comprised in the machine.

Similar letters of reference designate corresponding parts in all the figures.

As my invention is directed toward the pro duction of various mechanisms and devices which are necessary for the purpose of carrying a sensitized plate through the various operations and movements incident to the production of a completed photograph and its delivery to the outer portion of the machine and the adaptation of these parts as well to enable them to be operated in part by asnitable fluid under pressure I have shown such parts as are essential to my invention in detail. Other parts to which my invention does not relate are not so shown or are omitted altogether.

A is the inclosing box or chamber, within which the mechanisms and devices constituting the improvement are contained. It may be of any suitable shape or material and is provided in one of its walls with an inwardlyconvergent tube or light shaft A lenstube ll may be secured to the innerorsmallcr end of the light-shaft l and carries a suitable lens or arrangement of lenses B The light-shaft B is preferably convergent inward or cone-shaped, as this form will assist in the concentration of the light upon the lens 13 and permit of a considerable variation in the height of the subject posing in front of its outer orifice.

A plate-holder C is arranged at the rear of the lens 13 at such a distance therefrom that the image of the subject situated at a convenient distance in front of the orifice of the light-shaft 13 will be properly formed upon the sensitized plate contained within the plate-holder. A divergent tub'e C may be secured at the rear of lens tube B and extended rearward to the vicinity of the plateholder C.

D is a shallow box placed immediately at the rear of the lenstube l3. It may be socured to the lens-tube, while the divergent tube C may be attached to its opposite face. The box D is provided with an opening D in the extension of the focal-axis of the lens 13 the opening being controlled by a suitable shutter I, here shown as being sector-like in form and pivoted at its end portion within the box 1) by a pin (Z. The shutter D is provided with an arm d, extending on the side of the pin (I opposite to that on which the main body of the shutter is situated and suitably connected with the piston-rod (Z of an engine d, supported 011 one of the walls of the box D.

In the present instance for controlling the movements of the operative mechanisms 1 have shown engines which are provided with reciprocating pistons whose piston-rods are in direct engagement with the moving part or parts of the various mechanisms. These cylinders may be of the general construction represented in Fig. 6, in which E is a cylinder, E the reciprocating piston, c the pistonrod, attached to the piston and passing outward through. a suitable striding-box c at the end of the cylinder. A spring 6 may be utilized to return the piston to one end of its stroke. It is designed that the piston shall be moved in the direction opposite to that in which it is forced by the spring by a suitable fluid under pressure admitted to the cylinder, which after performing its function in moving the piston to the end of its stroke will be exhausted through a suitable duct or passage.

1 do not wish to be limited to the use of a spring as a retractive device, however, as other means or equivalents may be employed. For instance, a weight may be attached to the moving part by a cord running over suitable pulleys, or the spring may be placed outside the cylinder.

Any suitable fluid under pressure may be utilized for moving the pistons-for inst ancc, air or water, but I prefer air, making the machine thereby throughout pneumatically operated.

A convenient fran'iework or standard F is supplied for carrying and supporting the various parts of the machine.

G is a plate magazine or box carrying the supply of sensitized plates. t may consist of an oblong boy whose interior transverse dimensions correspond with the dimensions of the plates. The plates may be fitted in grooves 1 provided in the sides of the box to maintain them in an upright position.

G G are guidcways or tracks on which the magazine G may slide to and fro.

G is a chute secured below the magazine G, but independent therefrom and serving to direct the downwardly-moving plate from the magazine G to its proper position relatively to the lens 3 where it is held by the plate-holder C, presently to be described.

For the delivery of the plates from the magazine G one after another I contemplate in the present instance giving to the magazine a step-by-step movcmennthe d istanec the m a gazinc is carried at each step corresponding to the distance between the plates in the maga zine. The magazine G is provided with an independent bottom plate g, which is prevented from moving with the magazine G bya stop g, and consequently as the magazine is moved forward the plates will be delivered to the chute G in succession, descending through the latter to the plate-holder O.

I have showna convenient way of imparting to the magazine G a step-by-stcp movement. Its outer surface is provided with a series of ratchet-teeth (see Fig. t more especially,) with which engages a finger g, titted into a suitable opening in a pivoted lever 5 and thrust into engagement with the teeth by a spring 'ihe piston-rod g of a cylinder is adapted to swing the lever 9 about its pivot or fulcrum point g. It is evident that a reciprocation of the pistourod will impart to the magazine G an intcrmittent or step-by-step forward motion.

if it are retaining-jaws forming the plateholder 0 and serving to gras i the plate as it descends through the chute G and hold the same at the rear of the lens 13 he jaws are pivoted by pins h 7b to a supporting-plate 71, which is itself carried by a suitable appurtenance of the snpportirig-framework F. The inner ends of the pivoted jaws ll ll may be provided with pins 7:. 72. to engage with a notched plate 71., carried at the extremity of the piston-rod 7t of cylinder M. An outward movement of the piston of the cylinder 71: will effect a disengagement of and an inward movement of the same will effect an engagement with a plate interposed between the jaws ll ll.

I is a carrier, whose purpose is to depress and to withdraw the exposed plate into and out of the several solutions necessary for its development, fixing and washing, and finally to deliver the plate to a delivery-chute. It will be seen to comprise a slotted frame 1, through which the plate may move, and a holding-dog l, which is pivoted to the side of the frame and may be swung into and out of the slot to pinch the edges of the plate against the frame holding the plate or disengaging it from the plate entirely.

l is a cylinder carried by the frame 1, whose piston-rod 1' engages with an arm of the pivoted holding-dog l to swing the dog into and out of the slot of the frame I. A spring 1 may be used to insure the witht'lrawal of the dog I from the slot.

l I are upright cylinders attached to a sta tionary bracket and having piston-rods I? "i which engage with and give the carrier l a vertically-reciprocating motion.

The movements of the jaws ll ii, the frame I and the holding-dog l" are so timed that the dog will have forced the edges of the plate against the sides of the slot of frame I before the jaws ll. if have relinquished their hold upon the sides of the plate.

K is the movable bath or vessel for holding the various fluids to develop fix, and wash the exposed plate. .lt is shown in the form of abor; comprising four compartmen is K ii If? it". Thedevelopingand'lixingsolutionsmay be placed directly in compartments hi and K respectively, but I prefer to use separate cells for containing the solutions and insert the cells in the coinpa rtments.

'lhe movable bath h: is provided with suitable rollers 7; 7 7.; 7;, which travel upon a suitable track which may consist of the upturned leg of angle-irons 7;. 7.2. T he piston-rod 1i of cylinder K serves as a convenient means for causing the reciprocation of the bath K. The compartment K contains the washingwater, while the last compartment K" receives the washed and finished plate, from whence it passes to the delivery-chute L. The compartment K is provided with a slide L forming the bottom of the compartment, which may be moved to one side, permitting the developed and washed plate to fall through. This displacement of the slide L takes place when the compartment K is directly above the mouth of chute L. The slide L is pro vided with a tongue L which enters a recess in a block L secured to the under surface of the bath K. A spring Z continually presses the tongue L outward, tending to close the opening through the bottom of the compart ment K A stop Z is interposed in the path of a shoulder Z provided on the slide L.

The impetus of the bath K as it moves forward with the finished plate in compartment K" under the influence of the spring of cylinder K or other retractive device is sulficient as the stop Z and shoulder Z engage to compress the spring Z, carrying the slide L, from under the compartment K, when the plate passes downward to the delivery-chute L and thence outward.

I have shown a series of valves M M M M M M M M for controlling the flow of the motive fluid to and from the several cylinders for actuating the various mechanisms comprised in the machine. In the present instance I have shown a separate valve for each cylinder. Each valve may be carried on a bracket m, supported in any suitable manner. Each valve comprises a chambered block m, within which is fitted a rotary plug 172?, provided with a stem 017. A cover-plate m may be provided to inclose the plug m within the block 072. Each valve-block m is provided with three ports of 'm 072*, one, (see Fig. 2,) in the present instance m being at the top, while the remaining two, m m, are at opposite sides of the block. The port of at the inner side of the valve-block m of each of valves except valve M is continued through a suitable conduit m to a supplychamber M containing the motive fluid under pressure. The port m at the opposite side forms the exhaust, while the port m at the upper portion of the block is continued upward through a suitable conduit to the corresponding cylinder.

As illustrated, port m of valve M is eon tinned through a conduit m to the cylinder (1, whose piston actuates the shutter D Port m of valve h is continued through a conduit m which branches at its upper end and enters cylinders I I whose pistons actuate the carrier I. Port m of valve M is continued through a conduit m to the cylinder liwhose piston actuates the dog 1 Part of this cond uit will consist of flexible tubing to permit of the vertically-reeiprocating movement of the cylinder I as it moves to and fro with the carrier I. Port m of valve l\ 3 is continued through a conduit m to the water-compart ment K of the bath K. A portion of this conduit will also preferably consist of a flexible tubing to permit of the reciprocation of the bath. Port on of valve M is continued through a conduit m to the cylinder Zwhose piston actuates the plate-magazine G. Port m of valve I 5 is continued through a conduit m to the cylinder K whose piston aetuates the bath K. Port m of valve M is continued through a conduit m to the cylinder 7L5, whose piston actuates the jaws H II. Port m of valve M is continued through a conduit m to a cylinder N, whose piston may be utilized to actuate a slide N to control the slot or opening for the insertion of a coin. This slide may consist of a swinging arm, to which the piston-rod N of the piston with which the cylinder N is supplied engages to shift the slide across the slotopening to prevent the insertion of a second coin while the machine is in process of finishing an exposed plate. After the plate has been delivered the slide N will be swung to one side away from the slot-opening.

The rotary plug m comprised in each valve is provided with an angular passage 011 extending through it, which at one end of the movement of the plug will throw the ports m and m into communication and at the other end of its movement will throw the ports m and m into communication. Hence when the plug m of either of the valves M M M M M M ll M is moved to one end of the movement pressure will be admitted to the corresponding cylinder, while at the opposite end of its movement the motive fluid will be exhausted from the cylinders, the piston of which will be returned to its normal position under the influence of the spring or other retractive device.

For the purpose of operating the plugs m of the various valves I have supplied the stem m of each plug with a lever-arm O,whose free end is pivoted to one arm of an elbowlever 0. There are as many of these elbowlevers 0 and lever-arms O as there are stems m but for the sake of clearness in Fig. 1 I have shown but one but it-will be under stood that there is one for operating each plug m These elbow-levers O are fulcrumed to a shaft 0 carried in suitable brackets O 0, supported by the machine. The outer end of the free arms of each elbow-lever O is brought in to engagement with the periphery of a suitable peripheral cam by a spring 0". I have shown eight of these cams, one for actuating each elbow lever O and conse quently each plug m Cam P operates the plug m of valve M, cam P that of valve M, cam P that of valve M cam P that of valve M, cam I that of valve M, cam P that of valve M cam P that of valve M, and cam P that of valve M P is the cam-shaft to which the several cams are aiiiXed. It rotates in suitable bearings 1" P and is given an intermittent forward motion through the medium of a starwheel P attached at its extremity.

As the proper operation of the mechanisms comprised in the present invention will necessitate five distinct periods of rest, including that in which the parts have assumed their normal positions, comprising the exposure, the retention in the developing solution, the retention in the fixing solution, the washing and the return to the normal position assumed after the final deposition in the receivingcompartment of the bat-h K, and the movement of the bath forward depositing the finished plate into the delivery-chute L, I have divided the complete rotation of the cam-shaft I into five separate steps, separated by periods of rest. Consequently the star-wheel P will comprise five fingers or arms.

R is a disk provided with a series of pins 4, in the present instance comprising five, projecting from the inner radial face, the pins being adapted to contact with and impart to the star-wheel P an intermittent motion as the disk is rotated. These pins may be made adjustable, if desired, whereby ready means are offered for regulating the length of the periods of rest of the cam-shaft P I have shown a suitable motor for rotating the disk R. It is seen to comprise a drum It, within which may be coiled a spring (not shown) in the usual manner, a regulator R", a train of intermediate gearing R and a pair of bevelwheels R" It, for transmitting motion to the shaft 0' of the disk R. I have shown this form merely for illustration, but I do not wish to be confined to its use, as other forms and arrangements of driving mechanisms or motors may be advantageously utilized without departing from the spirit of my invention.

- S is a detent fitting into a notch or into notches of one or more of the moving parts of the motor, and when so engaged locking the same from movement. It may consist of a pivoted bar with one or more teeth. At its free end it extends immediately above one arm of a double-armed lever S, pivoted to a standard S The opposite arm of the doublearmed lever S is provided with a pocket 8, which is placed immediately below the lower end of the coin-chute S Normally the lever S is in a horizontal position, but when a coin is received through the chute S and drops into the pocket 3 the lever S becomes overbalanced, the en d carrying the coin descends, the opposite end ascends, raises the detentlever S, disengages the motor, which thereupon rotates the disk R and actuates the camshaft P lVhen the teeth of the detent-lever S are again in alinement with the notches provided for them, they reenter the same, locking the motor from further movement. The coin has in the meantime descended until the fioor of the pocket 8 has assumed a horizontal or slightly-inclined position, when the coin rolls out through the open end of the pocket 3 and drops into the casing A. The lever S then assumes its normal position.

T is a vibrating lever forming a latch fulcrumed at i to a pin carried by a bracket 1, attached to the framework l Its upper end is adapted to enter and withdraw from notches '6 provided in a plate i secured to the un' der side of the bath K. Its lower end contacts with pins or studs '5" t", provided on the cam P which operates to throw the upper end of the lever T out of engagement with the slots of plate 15 while a spring f is applied to withdraw it into engagement with the slots.

I have shown in Fig. 5 the several cams removed from their shaft and have also divided the angle subtended by the are traced by any point on the cam during a complete revolution of the latter-11am ely, three hundred and sixty degreesinto five equal parts, representing the five successive movements during the intermittent movement of the camshaft. Thus 1 2 represent the movement during the first fifth of the full rotation; 2 3, that during the second fifth; 3 4:, that during the third fifth; at 5, that during the fourth fifth, and 5 1 that during the last fifth. I have also shown the free end of each elbowlever O in the position which it assumes in the machine relatively to its respective cam.

\Vith the assistance of the figure the operation and sequence of movement may be described as follows: Assuming that a coin has been deposited in the coin-slot, has descended the chute S and passed into the pockets, thus disengaging the motor in the manner already described, the disk R revolved, and the first pin 7' of the same contacts with one of the fingers of the star-wheel P Before any movement has taken place the cams and ends of elbow-levers O are in the relative positions shown in Fig. 5. During the first fifth of the complete rotation of the camshaft P namely, from 1 to 2which terminates after the first pin has passed out of contact with the first finger of the star-wheel, cam P operates to rotate the plugm" of valve M to open communication between the ports m and m of said valve. This movement takes place owing to the fact that cam I is reduced in diameter for a portion of its circumference, the free end of the elbow-lever dropping into the recess produced by this redueed portion and shifting the plug of the valve in a manner evident from the foregoing description. By this movement the motive fluid is admitted to cylinder (1 and the shutterD is opened and held open for a space of time almost equal to a fifth of the revolution of the cam. Just before the cam reaches the end of its first movement the elbow-lever O is shifted back to its original position, thereby throwing ports m and m in communication, when the motive fluid is exhausted from cylinder (Z and the shutter D is moved back to its normal position, closing the opening for the exposure of the plate.

It is evi- IIO dent that during this portion of the movement no function is performed by cams P, P P and P Cam P, however, is provided with a notch in its periphery between points 1 2. Consequently during this movement plug m of valve M will be operated to admit the mo tive fluid to and exhaust it from cylinder 9 This will operate in the manner already explained to carry the platemagazine forward and deliver a plate to the carrier 0. 0n comparison of cams P and P, as represented in Fig. 5, it is evident that cam P will operate before cam P. Hence before the shutter D is moved to one side a plate will have descended into the holder 0. Immediately after the operating-motor of the machine has been set in motion by the insertion of a coin cam P will operate to admit the motor fluid to cylinder N, shifting the slide N across the coin-slot and closing the same. It will preferably remain closed during the entire operation of the machine. The several cams will now remain in the same position where the free ends of the elbow-levers O are at the point 2 until the second pin of disk It will have contacted with the second finger of star wheel P During the movement 2 8 cams P P P P are inoperative. (Jam P will be the first to operate during this movement. It will operate the plug m of valve M to admit the motive fluid to cylinder 1 thrusting in dog I to grasp the plate in carrier I by its upper edges. It will be thus held during the succeeding manipulations of the plate. Cam P will be the next to operate, shifting the plug m of valve M to admit the motive fluid to cylinder 71, releasing the grip of the jaws H H upon the plate. Lastly, just before the camshaft comes to rest, due to the passing of the second pin on disk It out of engagement with the second finger of star-wheel P" cam P will operate to shift the plug m of valve ll admitting the motive fluid to cylinders I 1*, which move the carrier 1 downward and thrusts the plate into the developing solution carried in compartment K. The various cams have now reached position 3, and the plate is held suspended in the developing solution until the third pin of disk R has contacted with the third finger of the star-wheel'P Immediately upon the com meneement of the movement 3 a pressure is released from the cylinders I I and the carrier I is drawn upward by the spring within the cylinder or other retractive device, and the operation of cam P soon follows to shift the plug m of valve M to admit the motive fluid to cylinder K to move the bath K backward from the position shown in Fig. 1, so that the fixing solution carried in compartment K sh all be immediately below the platecarrier 1. To permitof this backward movement of the bath, it must be unlocked from latch T. To this end the pins 25 1 extending from cam P are so arranged that one of them has oscillated the latch on its pivot- 3i to throw it out from engagement with. a slot in the plate i affixed to the bath K, but has left it free to be withdrawn into the next slot by the spring L. Pressure may be kept upon the piston of cylinder K during the remainder of the operation of the machine and its move ment controlled by the latch T. The cams have now completed the third fifth of their movement and the carrier I has descended with the plate into the fixing solution carried by compartment 1 in which it is held suspended until the fourth pin of disk R has moved into engagement with the fourth finger of star-wheel P The movement represented by l 5 now takes place. Bath K is released, shifted backward a step to bring the water compartment under the carrier by the oscillation of latch T by a second pin on cam P, as already described. At the completion of this movement the carrier I and the plate held therein descends into the washing-water in compartment K as is evident from the construction of cam P, and is there held until the fifth pin of disk R has moved into engagement with the fifth finger of the star-wheel P Atthe completion of the fourth fifth of the movement cam P also becomes operative, as it is provided with a notch on the radial line 5. It operates to shift the plug m of valve M, admitting water to the compartment.

It is not essential that there should be a separate cylinder for controlling the cock for the inflow of water. If water is used as the motive fluid for the cylinders, port on of the valve M will be permanently closed and the construction of the plug and the valve may be otherwise the same as the other plugs and valve-blocks. If air is used, the port m may be permanently closed and a water-supply connected with port HY/ or port m may be closed and water-supply connected with the port m. Of course the various parts connected to the plug m of this valve will be properly related to open and close the valve at the proper time. A flexible tube V carries off the overflow from chamber K. Further movement of the motor carries the fifth pin of disk It into contact with fifth finger of the star-wheel P and the cam-shaft has commenced the movement 5 1. Cam P operates to withdraw the plate from the compartment K", cam P to shut off the flow of water, and the latch T is withdrawn to permit the back ward movement of the bath to its farthest backward position, in which compartment K" of the bath is directly under the plate. The dog I is now released by the action of cam P the suspended plate drops into compartment, and the jaws ll ll come together to receive and support the next plate through the action of cam P", which operates to release the pressure from cylinder 7L5, the piston of the same being thus forced outward in a manner well understood. Further rotation of the camshaft P releases the pressure from cylinder K through the means of cam P and interme diate mechanism. The bath K is carried for c senses ward by the retractive device to the position shown in Fig. 1, the slide 'L is drawn aside, and the finished plate descends through the delivery-chute in a manner already described. Before the cam-shalt has completed its movement the pressure has been released from cylinder N and the slide withdrawn from the coiirslot. The parts have now returned to their original position and are ready to again be set in operation by the insertion of a new coin.
